The invention relates to a method for detecting titanium dioxide in an HIPS (High Impact Polystyrene) resin system, in particular to a method for detecting the lightening power of titanium dioxide in the HIPS resin system, which is simple in formula, easy to operate, low in cost, capable of reflecting the original performance of titanium dioxide, short in detection period, good in detection data reproducibility and reliable in result. After drying treatment, cooling for use; b, uniformly mixing the weighed titanium dioxide, HIPS resin, dispersant and carbon black in an automatic mixer to obtain a sample; and c, the sample plate is prepared from the uniformly mixed sample in the step b through an injection molding machine, the temperature of the injection molding machine is 150-280 DEG C, the injection molding pressure is 30-100 bar, and the fading power of the prepared injection molding plate sample plate is detected, so that the fading power parameters of the injection molding plate sample plate are obtained
